The Molecular Gastronomy of Chocolate

~60 min · 15 stations

The Molecular Gastronomy of Chocolate is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify the primary chemical compounds found inside natural fermented cacao beans; explain the historical evolution of turning cacao into edible solid chocolate; analyze the molecular structure of fats found in cocoa butter.
